On Tuesday, Gaga posted a photo (left) of herself wearing nothing but a yellow bra and underwear, along with this caption: “Bulimia and anorexia since I was 15.” With the picture, she announced the launch of a new movement, “A Body Revolution 2013,” meant to encourage body acceptance.

On her site, Gaga explains that the inspiration behind the movement stemmed from the Born This Way Foundation, an organization she started with her mother to stop bullying and embrace individuality. “This profile is an extension of that dream,” she wrote. “Be brave and celebrate with us your ‘perceived flaws,’ as society tells us. May we make our flaws famous, and thus redefine the heinous.”

Unsurprisingly, the Mother Monster’s positive message resonated with her Little Monsters. Soon after the post went up, fans began flooding the website with photos of themselves in their underwear and sharing their own personal struggles with body image issues.

“I have been startled and overwhelmed with pride and emotion the past few days. Gratitude mostly,” Gaga wrote in a letter to her fans, thanking them for their outpouring of support for her cause. “You are proud to be born this way, and brave in your vulnerability with this community. Watching you all create a safe space online for people to be compassionate is the greatest gift you could ever give me.” Tell us: What do you think of Gaga’s Body Revolution? Do you think that this was the right way to respond to the haters?
